I am trying to upload an image to my database using jsp. I want to store the image in a folder called Upload and want to insert the image name in the database. I used a servlet to do this.
I uses seperate pages for input, action and database connection and I explain the code below.
Photo.jsp
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body><form name="f" action="uploadimage" method="post" enctype="multipart/form-data">
<table>
<tr><td>
Name</td><td><input type="text" name="name"/></td></tr>
<tr><td> Address</td><td><textarea name="addr" rows="10" cols="10"></textarea></td></tr>
<tr> <td><input type="file" name="f1"></td></tr>
<tr><td colspan="2"><input type="submit" name="b1"></td></tr></table> </form>
</body>
</html>
My database connection is given below:
public int insert_file(String name, String addr, String img)
{
int i=0;
System.out.println("inside insert_file");
try
{
Connection con21=get_con();
System.out.print(con21);
Statement s21=con21.createStatement();
String s11="insert into image(name,addr,image) values ('"+name+"','"+addr+"','"+img+"')";
System.out.println("i"+s11);
i=s21.executeUpdate(s11);
System.out.println(i);
}
catch(Exception e)
{
System.out.println(e);
}
return i;
}

My problem is that the code is running, but it does not do what I want. The first print statement in the try clause are printed successfully.
I resolve my problem... I change the package "import org.apache.tomcat.util.http.fileupload.FileItem;" into "import org.apache.commons.fileupload.FileItem;".
now it running well....

entry_page_gen.java is stored in a package called Servlets.
What's going wrong? If more information is needed, please ask. I didn't want to bog down the question with info that might not be needed.
A point to note is that if I change the Web.xml -> <servlet-mapping> -> <url-pattern> to /entry_page_gen and call the servlet from a <form> with the action parameter, everything works fine.
P.S: I referred to this question while creating the above pieces of code.
Well here is a solution for you.
entry_page_gen.java (By the way you should change this name to follow the java convention)
#Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//processRequest(request, response);
response.sendRedirect("hello.html");
return;
}
Configuration:
Output:
Notes:
In the image you are seeing the URL http://localhost:8080/web-project/hello.html because of the redirect in the method, but you can reach this element with: http://localhost:8080/web-project/entry
The explanation of the configuration could see here:
https://stackoverflow.com/a/26329628/1670134
As answered in here, the initial slash character refers to the path from the base URL (by default the domain name, unless changed with a <base> HTML element). So if your app URL is http://www.example.com/myapp, then an anchor 1 will refer to http://www.example.com/entry/test.html, therefore the servlet is not called.
You could change the anchor's href to this 1

I am trying to check the existing data in database and insert the record.In the above try to execute it shows the blank page.
before insert command is worked but we adding the select command its not working.
using the select command for the check the database and in case any data existing the database it shows the record is already exist ,please choose the another name.
In case of no duplicate data not found,insert command perform the action and insert the new record into the database and it shows the new record in to database successfully.
But my code is not working for the properly.
thank you.
You have mistake in your code :
PreparedStatement pstmt=con.prepareStatement("select * from headwy where unmae=? " );
check your column name its "uname" not "unmae".
There are multiple issues in your code. First there is a typo. If that is the reason for failure.
select * from headwy where unmae=?
insert into headwwy (phone,uname,pass) values(?,?,?)
Also
pstmt.executeQuery("insertquery");
should be executed after you have set the parameters
pstmt.setString(1,phone);
pstmt.setString(2,username);
pstmt.setString(3,password);
I'll recommend to go through JDBC tutorial and run again.
You should set the parameters in your preparedstatement before executing your preparedstatement.
PreparedStatement pstmt=con.prepareStatement("select * from headwy where unmae=? " );
pstmt.setString(1,username);
ResultSet rs = pstmt.executeQuery();
if(rs.next())
{
System.out.print("username already exist");
}

It's showing the following error:

where mummy is the retrieved attribute("uname") ?
I am new in jsp/servlets so kindly explain what should I do to make it work.
There is no syntax insert into ...values .. where defined
looks like you want to update a column, so you have to use:
Update signup set dp =? where signup.name = ?
For more information about update syntax look in the official mysql documantation
I have an HTML form that uses 'POST' to send parameters to a servlet. When I use a computer the form works for both 'GET' and 'POST' methods. However, on certain mobile phones there are no parameters passed to the servlet when using 'POST'. It does work on mobile phones when using the 'GET' method.
I have tested it on an iPhone 5C (iOS7), iPhone 4 (iOS 6), Samsung Galaxy S3 (Android 4.4.2), Samsung Galaxy S4 (Android 4.4.2), and LG G2 (Android 4.4.2).
It works unreliably when using the Google Chrome mobile browser, but not at all when using the default browser installed. Does anyone know how to make it work for the native browsers?
Thanks!
Below is the code for a simplified version of the error. The form posts to the servlet that prints to the browser all parameters. It is hosted on an Amazon Web Services Elastic Beanstalk running Tomcat 8 Java 8.
The deployed example can also be viewed here:
http://centum2-env-bc2wqa62ib.elasticbeanstalk.com/
On mobile browsers, only the word "Parameters" is printed to the browser.

I want to upload a file in apache tomcat and save data in the MySQL from text field using JSP. On doing so, I could not pass the value from JSP page to Servlet and save in Database.
How can I do it?
I tried the following lines of code:
JSP:
<form action="UploadServlet" method="post"
enctype="multipart/form-data">
<input type="file" name="file" size="50" />
<br />
<input name="a" type="text"/>

How can I do this.
Create file object that points to a file specified by you in JSP.
and in JSP do,
request.setAttribute("file",fileObject);
and in Servlet get that object using
request.getAttribute("file");
try this.it should work.
To send a file through a JSP/servlet we need a commonsio.jar file and this will be easily found in the google. Now place that jar file in the lib directory of the tomcat folder and Now it will work.
